Description

Compositions for promoting plant rooting and rooting promoters applied to flowers and trees, soil conditioners, landscaping plantings

The present invention relates to a composition for promoting the growth of plant roots and a rooting promoter comprising the same.

In agriculture, controlling plant growth is an important technique for improving productivity. Currently, various types of plant growth regulators for the purpose of suppressing or promoting plant growth are put into practical use, contributing to the improvement of crop yields and product quality.

However, plant growth regulators that promote root development are few in number, have insufficient effectiveness, and have undesirable effects in some cases. For example, auxin-based compounds, which are currently widely used as rooting promoters, can cause growth of leaf tops, stem torsion, and even death of plants if used incorrectly depending on the type or condition of the plant and the concentration used. Since it may have an undesirable action, there are restrictions on the method of use and the amount used, and the action of promoting root development was not sufficiently satisfactory.

Recently, in the field of promoting plant rooting, several natural and synthetic substances, including auxins, which are plant hormones, have been used in order to expect better rooting promoting effects than before.

However, the effect by these was also not sufficient, and there was a problem in terms of harmfulness to the human body. In this regard, a material that is effective in promoting plant rooting and is hygienically safe has been required.

The present invention is to newly propose results obtained through research on combinations of various components in order to prepare a rooting promoter that is environmentally friendly and can be easily manufactured and can help plant root growth.

A composition for promoting rooting for plant root growth according to an embodiment of the present invention includes 5% to 10% by weight of an aqueous dispersion of seaweed extract containing alginate; 5% to 10% by weight of an aqueous dispersion of sericite; 1% to 10% by weight of an aqueous dispersion of lignin conversion; 15% to 20% by weight of an aqueous dispersion of biochar; 1% to 2% by weight of sea salt; 1% to 3% by weight of calcium sulfate; 1% to 5% by weight of humic acid; 1% to 3% by weight of a rooting promoting hormone containing at least one of indole butyric acid (IBA) and benzylaminopurine (BAP); and a liquid fertilizer containing the rest of the animal amino acids and polyphenol compounds.

According to one embodiment, the aqueous dispersion of the lignin convertor may be prepared by inoculating lignin with at least one of rot fungi, Ganoderma lucidum, and Epax lacteus and fermenting the lignin.

According to one embodiment, the rooting promoting hormone agent may be a mixture of indolebutyric acid and benzylaminopurine at a weight ratio of 2:1 to 3:1.

According to one embodiment, the liquid fertilizer may further include at least one of phenyl lactic acid or a salt thereof and methionine or a salt thereof.

According to one embodiment, the biochar may include pulverized particles of eucalyptus carbide.

According to one embodiment, the polyphenol compound is a tea-derived polyphenol compound, and may be at least one selected from the group consisting of catechin compounds and their isomers, theaflavin compounds, and thearubigin compounds.

A rooting promoter for plant root growth according to another embodiment of the present invention includes the composition for promoting rooting.

A soil improver for plant root growth according to another embodiment of the present invention includes the composition for promoting rooting.

The composition for promoting rooting for plant root growth proposed in the embodiments of the present invention can be used not only as a rooting promoter, but also for flowers, trees, soil conditioners and landscape plantings to which the composition for promoting rooting can be applied.

The composition for promoting rooting for plant root growth proposed in the embodiments of the present invention may be applied in a form of spraying directly to flowers or trees of plants in a liquid form.

The rooting promoter to be proposed in the present invention is harmless not only to plants but also to the human body handling the rooting promoter, and can be expected to greatly help plant root growth compared to conventional rooting promoters.

Plant rooting promoters prepared according to an example of the present invention can be easily manufactured because they can be found in everyday materials, but are less concerned about side effects on the human body, so they are more environmentally friendly than existing rooting promoters and are suitable for growing edible crops. convenient to use

In addition, only the use of a low concentration induces the generation of fine roots and protects them from the risk of growth, thereby obtaining a high rooting promotion effect, which has a practical and very effective advantage.

According to one example, the effect can be expected even when the rooting promoter of the present invention is used in the form of spraying on flowers or trees in liquid form.

A composition for promoting rooting for plant root growth according to an embodiment of the present invention includes 5% to 10% by weight of an aqueous dispersion of seaweed extract containing alginate; 5% to 10% by weight of an aqueous dispersion of sericite; 1% to 10% by weight of an aqueous dispersion of lignin conversion; 15% to 20% by weight of an aqueous dispersion of biochar; 1% to 2% by weight of sea salt; 1% to 3% by weight of calcium sulfate; 1% to 5% by weight of humic acid; 1% to 3% by weight of a rooting promoting hormone containing indole butyric acid (IBA) and 6-benzylaminopurine (6-BAP); and a liquid fertilizer containing the rest of the animal amino acids and polyphenol compounds.

The seaweed extract containing the alginate is a high-molecular polysaccharide and can promote plant growth through natural plant hormones and natural minerals. As an example, the seaweed extract may be prepared by pulverizing bull-kelp, that is, kelp, a natural resource of the sea, using a high-pressure extraction method or a freeze-drying method. As described above, the seaweed extract is a natural substance containing a large amount of natural plant hormones and natural minerals, and has an excellent effect on promoting plant growth, such as strengthening the ability to withstand adverse external environments, in addition to the effect of promoting rooting of trees during planting work.

The alginate can help to promote growth in plants, develop fine roots of plants, and bind soil, microorganisms and roots so that constant growth can proceed even in a humid or dry external environment.

The aqueous dispersion of sericite may be an aqueous dispersion containing 15% to 30% by weight of sericite. Sericite is a clay mineral with a chemical composition generally composed of SiO2, Al2O3, Fe2O3, CaO, K2O, Na2O, etc., and having high plasticity. The sericite component may be used as an inorganic material source for forming an organic-inorganic composite in the present invention. The sericite may be pulverized to a particle size of several μm to several tens of μm.

At this time, the sericite may combine with the seaweed extract to form an organic-inorganic complex in which organic and inorganic substances are integrated. The organic-inorganic complex formed in this way may inject nutrients into the soil and at the same time improve the air permeability and moisture retention of the soil.

According to one embodiment, the aqueous dispersion of the lignin convertor may be prepared by inoculating lignin with a specific component and fermenting the aqueous dispersion.

For example, the lignin transformant may be inoculated with a decaying fungus and fermented. As another example, the lignin transformant may be obtained by inoculating lignin with Ganoderma lucidum or Epax lacteus and fermenting the lignin. The Ganoderma lucidum may be extracted from Ganoderma lucidum, and the Ipax lacteus may be extracted from chinensis mushroom. As another example, the lignin transformant may be obtained by inoculating and fermenting two or more selected from the group consisting of rot bacteria, Ganoderma lucidum, and Ipax lacteus together. The fermented lignin transformant may then be dispersed in water and included in the composition for promoting rooting.

For the experiment, the present inventors tested the rotting bacteria, Ganoderma lucidum (Ganoderma lucidum) KACC 42231 or Irpex lacteus (Mechanism mushroom) KACC 43133 in 100 mL of PDB containing lignin powder ( Potato dextrose broth) medium was inoculated to obtain a lignin transformant, through which the effect of promoting plant root growth was confirmed.

After culturing the decayed bacteria at 30 ° C. for about 3 weeks, the mycelium was pulverized with a blender and centrifuged, and the supernatant was measured at 450 nm. As a result, it was confirmed that when the lignin transformant was prepared from lignin through fermentation of the fungus, the 450 nm wavelength rapidly increased, and through this, it was confirmed that the transformation into the lignin transformant occurred.

Thereafter, the lettuce seedlings germinated in the same size were transferred to MS solid medium, which is a plant nutrient medium containing the lignin convertor powder, and grown for about 2 weeks, and then the root part was harvested and the length of the main root was measured. As a result, lignin conversion When the sprouted lettuce seedlings were grown in a plant nutrient medium containing a sieve, it was confirmed that the growth of roots was markedly increased compared to the control in which no lignin transformant was added.

According to one embodiment, the rooting promoting hormone agent may have a weight ratio of indolebutyric acid:benzylaminopurine of 2:1 to 3:1.

The rooting promoting hormone agent is not limited as long as it is a hormone component that is usually added to promote rooting, and may include various components, but according to one example, it may include indolebutyric acid and benzylaminopurine.

The indole butyric acid is a hormone that promotes the rooting of another root, and is a plant hormone of the Auxin system and has an excellent effect on rooting. When the indole butyric acid is included together with benzylaminopurine to be described later, a complementary effect can be expected.

The indole butyric acid is one of the auxins found naturally, and can be isolated from leaves and seeds of plants such as corn, and can be chemically synthesized at a certain concentration and method if necessary.

The benzylaminopurine is one of the plant hormones of the cytokinin family known to have a function of differentiating leaves. Since the cytokinin has a purine nucleus, it may promote the formation of negative stems as a plant growth regulator that promotes cell division. The benzylaminopurine has the advantage of generating many new roots when used during rooting, and may be a substance that exhibits the strongest cytokinin activity among homologues having a chemical structure similar to kinetin. The benzylaminopurine may be 6-benzylaminopurine, and 6-benzylaminopurine is a substance that is also used to stabilize the effect of promoting unnuclear hyperplasia and hypertrophy of grapes by gibberellin treatment.

It is preferable that the indolebutyric acid and the benzylaminopurine are included together in an appropriate weight ratio. When the mixing ratio of the two compounds is less than 2:1, rooting promotion is somewhat difficult, and indolebutyric acid is less than 3:1. If the content of is increased, there is a fear of causing deformity of the tree.

According to one embodiment, the liquid fertilizer may further include at least one of phenyl lactic acid or a salt thereof and methionine or a salt thereof.

Ethylene is known to have a rooting promoting effect depending on the type of plant or its condition, whereas the rooting effect of methionine, its precursor, has not received attention. In particular, it was known that injecting high concentrations of methionine into the soil rather inhibited the growth of roots. However, the present inventors found that there was a rooting promoting effect when phenyl lactic acid and methionine were mixed with other substances in an appropriate amount, and confirmed this through experiments.

The above-mentioned methionine may be secured from a commercial product, or one produced by organic synthesis or microbial fermentation may be used. In addition, a composition containing methionine or a salt thereof may be used, and for example, a fermentation broth of microorganisms containing methionine, a protein peptide containing methionine as a component (so-called protein form) or a decomposition product thereof may be used.

The methionine salt is not particularly limited in the present invention, but alkali metal salts such as sodium and potassium; alkaline earth metal salts such as calcium and magnesium; organic acid salts such as ammonia; citric acid, tartaric acid, oxalic acid, lactic acid, and acetic acid; Mineral salts, such as phosphoric acid, carbonic acid, nitric acid, sulfuric acid, hydrochloric acid, etc., are mentioned. At least one of the phenyl lactic acid or a salt thereof and the methionine or a salt thereof may be included in the liquid fertilizer at a concentration of 10 ppm to 1000 ppm.

According to one embodiment, the biochar may include pulverized particles of eucalyptus carbide.

The eucalyptus carbide may be obtained by drying Eucalyptus globulus; Peeling the dried eucalyptus to remove the bark; crushing the peeled eucalyptus; It may be prepared including; carbonizing the pulverized eucalyptus to produce biochar.

The drying step may be drying leaving only 10% to 20% of the moisture content of the eucalyptus, and drying to 15% to 20% in summer and 10% to 15% in winter to adjust the moisture content. As described above, there is an advantage of minimizing the generation of water vapor generated in the thermal decomposition process through moisture drying and preventing loss of organic substances released through biogas. The carbonization may include carbonizing the pulverized eucalyptus at a temperature of 300° C. to 500° C. by an external heating source. The carbide prepared through this may be pulverized to a diameter of several tens of μm to several hundred μm and then mixed with the composition for promoting rooting. When the carbide is pulverized to less than a few tens of μm, the rooting promotion performance may deteriorate, and when the carbide is pulverized to more than a few hundred μm, uniform dispersion is not achieved and heat transfer is not smooth, so that the homogeneous carbonization process in the thermal decomposition process may be hindered. can

At this time, the carbonization may be to carbonize the pulverized eucalyptus at a temperature of 300° C. to 400° C. for 12 hours to 18 hours in an anoxic condition in an indirect heating method by an external heating source. The pulverized eucalyptus is carbonized, and in the pyrolysis process, the carbonization is performed in a torrefaction form rather than complete carbonization, and through the carbonization process, components such as oil, resin, and sugar present in the eucalyptus are Mutations can be made to components that promote plant root growth.

According to one embodiment, the polyphenol compounds are tea-derived polyphenol compounds, and may be at least one selected from the group consisting of catechin compounds and their isomers, theaflavin compounds, and thearubigin compounds.

Conventionally, polyphenolic compounds are known as components that inhibit plant root growth, but it has recently been known that polyphenolic compounds derived from tea have an elongation-stimulating effect on plant roots when they are contained in low concentrations, contrary to conventional knowledge. there is a bar Tea polyphenols are active ingredients of tea that have been used as beverages since ancient times, and are environmentally friendly and very safe substances. The tea-derived polyphenols can be prepared from tea leaves as a raw material, and according to one example, the present invention can use them by dissolving them in water or the like. The concentration of the tea-derived polyphenols may be preferably 0.01 ppm to 500 ppm.

A rooting promoter for plant root growth according to another embodiment of the present invention includes the composition for promoting rooting.

The rooting promoter may be used through a method of directly or indirectly fertilizing the soil of the plant. This can be done by drenching the plant, i.e. by spraying or by immersion. The 'fertilization' refers to a farming method that promotes the growth of crops by supplying fertilizer components to soil or crops. It doesn't work.

In the case of the immersion method, the composition may be poured into the soil around the plant or the seed may be immersed in the composition, but is not limited thereto.

The rooting promoter may be formulated in various forms such as powder, pellets or granules of an appropriate size using a general formulation machine, in addition to being prepared in a liquid form, but is not limited thereto.

When formulated and used as described above, the rooting promoter composition of the present invention may be used as it is or dried at room temperature by air drying, freeze drying or high temperature drying. In order to properly use the liquid fertilizer composition in farms, it should not be precipitated as a usable pH range for crops. The mixing ratio should be determined by considering the pH and solubility of the raw materials used.

When the composition proposed in the present invention is applied as a rooting promoter for plants, root mass and root density are increased through the increase in the number of side shoots and side shoots and the number of side shoots. , improvement of absorptivity, improvement of absorptive power, improvement of fertilizer component utilization rate, green support, improvement of photosynthetic ability, improvement of water stress resistance, prevention of lodging, increase of yield, etc. can be obtained.

As an example, the plant to which the composition for promoting rooting of the present invention is applied is not particularly limited, but examples include eggplants such as tomatoes, green peppers, red peppers, and eggplants, cucumbers, pumpkins, melons, and watermelons. Fresh vegetables such as celery, parsley, and lettuce, spicy vegetables such as green onions, onions, and garlic, beans such as soybeans, peanuts, kidney beans, peas, and red beans, other fruits and vegetables such as strawberries, radishes, stumps, carrots, and burdock. Straight roots, taro, cassava, potato, sweet potato, sap such as Nagaimo, asparagus, spinach, rapeseeds such as greens, torkogikyo, stock, carnations, flowers such as chrysanthemum, rice, wheat, barley, oatmeal, corn Grains such as back, grasses such as bentgrass and kouraishiba, oil crops such as rapeseed and sunflower, sugar crops such as sugarcane and sugar beets, fiber crops such as cotton and sirloin, clover, sorghum and forage crops such as dent cones, deciduous fruit trees such as apples, pears, grapes, and peaches, citrus fruits such as tangerines, lemons, and grapefruits, and various other types of flowers and trees, landscaping plantings, and the like.

As an example, the composition for promoting rooting of the present invention may be prepared in a solid form and included in a soil improving agent.

The composition for promoting rooting for plant root growth proposed in the embodiments of the present invention can be used not only as a rooting promoter, but also for flowers, trees, soil conditioners and landscape plantings to which the composition for promoting rooting can be applied.
